Abstract:The spectrum refers to the representation of a signal in time domain in frequency domain, which can be obtained by Fourier transform. The result is two graphs with amplitude and phase as the longitudinal axis and frequency as the transverse axis respectively. If the signal changes with ...
Spectral estimate methods try to infer the\nmodulating signal characteristics from the available beat timing on the\nECG signal. These methods usually estimate the spectrum through the\nheart period (HP) or the heart rate (HR) signals. In this work, the\nauthors introduce a new HRV signal, ...
